* Salivary glands: Secrete salivary amylase, which begins the breakdown of carbohydrates in the mouth.

* Stomach: Secretes gastric juice, which contains pepsin (breaks down proteins), gastric lipase (breaks down fats), and hydrochloric acid (activates pepsin and provides an acidic environment).

* Pancreas: Secretes pancreatic juice into the small intestine containing:

* Pancreatic amylase: Breaks down carbohydrates.

* Trypsin and chymotrypsin: Break down proteins.

* Pancreatic lipase: Breaks down fats.

* Nucleases: Break down nucleic acids.

* Small intestine: While not a gland itself, the small intestine secretes enzymes directly into the intestinal lumen, including:

* Lactase: Breaks down lactose.

* Sucrase: Breaks down sucrose.

* Maltase: Breaks down maltose.

It's important to note that these are just the major digestive enzymes secreted by these glands. There are other enzymes involved in digestion, and the specific enzymes produced can vary slightly between individuals.
